目的:探讨血液酒精浓度(BAC)与酒后交通肇事的相关性,为预防和控制酒后驾车提供科学数据。方法:对2007~2008年江门市1518例涉嫌酒后交通肇事者的年龄、性别、各时间段BAC分布等进行分析。结果:1518例涉嫌酒后交通肇事者中20岁~50岁1330例,占87.6%;男性1368例,占90.1%。BAC“异常”者55.1%,其中“饮酒”驾车者11.5%、“醉酒”驾车者40.7%。2008年度交通肇事者BAC“异常”者59.8%,明显多于2007年度的51.4%,有统计学意义(2χ=10.6907,P<0.01);“饮酒”者与2007年度比较无统计学意义(2χ=0.3152,P>0.05);“醉酒”者45.8%明显多于2007年度的36.6%,有统计学意义(2χ=13.1051,P<0.01);“饮酒/醉酒”者56.8%明显多于2007年的48.6%,有统计学意义(2χ=10.2505,P<0.01)。2007~2008年国家法定节假周休日涉嫌酒后交通肇事者日均2.39例,多于非法定节假周休日的日均1.93例,有统计学意义(t=15.9534,P<0.01)。结论:酒后驾车以中青年男性为主,以国家法定节假周休日多见,酒后驾车呈现上升趋势,应加强对酒后驾车的预防和控制。
Objective: To investigate the correlation between blood alcohol concentration (BAC) and traffic accident after drinking to provide scientific data for prevention and control of drunk driving. Methods: The age, sex and BAC distribution of 1518 suspected drinkers in Jiangmen City from 2007 to 2008 were analyzed. Results: Among 1518 suspected drunk traffic accident victims, 1330 cases were 20 years old to 50 years old, accounting for 87.6%; 1368 were male, accounting for 90.1%. 55.1% of BAC “anomalies ”, among which 11.5% were drivers of drinking alcohol and 40.7% of drivers were drunk. The number of traffic perpetrators in BAC in 2008 was 59.8%, significantly higher than 51.4% in 2007 (2χ = 10.6907, P <0.01). There was no statistical difference between 2007 and 2007 (2χ = 0.3152, P> 0.05); 45.8% of drunken people were significantly more than 36.6% of 2007 (2χ = 13.1051, P <0.01) 56.8% were significantly more than 48.6% in 2007, with statistical significance (2χ = 10.2505, P <0.01). There were 2.39 cases of perpetrators of drink-traffic accidents on statutory holidays on weekdays in 2007-2008, more than the average of 1.93 cases on non-statutory holidays each week (t = 15.9534, P <0.01). Conclusion: Drunk driving is dominated by middle-aged and young men. It is more common on national holidays and weekends and drunk driving presents an upward trend. Prevention and control of drunk driving should be strengthened.
